巴陵石化己内酯介绍

己内酯是一种无毒的有机化工中间体，具有优异性能和绿色环保的特性。由于己内酯制备对原料质量要求高、工艺路线长、安全要求高，技术难度大，目前国内外只有为数不多的几家企业生产，且主要集中在英、日、美等发达国家。国外己内酯生产企业总产能在5万～7万吨/年。近年来，随着己内酯及下游产品的应用领域不断扩大，己内酯单体的市场需求量也逐年增加。而随着国内企业筹划加入生产行列，己内酯在我国的应用可望加速。

Baling Petrochemical caprolactone introduction

Caprolactone is a non-toxic organic chemical intermediates, characteristics of excellent performance and green environmental protection. Because of caprolactone preparation requirements high, long process, high security requirements on the quality of raw materials, technical difficulty, currently only for a few enterprises few production, and mainly concentrated in developed countries, Japan and U.S.A, britain. Foreign caprolactone production enterprises a total capacity of 50000 ~ 70000 tons / year. In recent years, with the application fields of caprolactone and downstream products continues to expand, caprolactone monomer market demand has increased year by year. But along with the domestic enterprises planning to join the ranks of production, caprolactone acceleration can be applied in our country.
